Please tell the proverbs of three natural phenomena and their scientific reasons.

Earthworms sealed the hole and it rained heavily. ""bees come home late, and the rain comes and the wind blows. " "The ants move, it's going to rain. "

Meteorologists explained that this is because the air pressure is low when it is about to rain, and small insects are sensitive to this change, so they are prepared.

"The oxtail points to the west and the weather is fine; The oxtail points to the east, and heavy rain is coming. "

It is said that cows don't like to face strong winds, and they like to clip their tails. It is similar to a dull weather vane. It's sunny when its tail is facing the strong west wind. The tail points to the east, indicating that the wind rotates counterclockwise in the center of low pressure, and it may rain.

There is a rainy mountain with a hat, and there are no rain clouds.

Clouds cover the top of the mountain, which is called "the mountain wears a hat". Clouds block the mountainside and you can see the top of the mountain, which is called "clouds in the middle".

When rainy weather comes, the clouds are very low and the bottom of the clouds covers the top of the mountain. The thicker the clouds are, the lower the clouds are, indicating that the more water vapor in the air, the easier it is to form rainy days. However, if the mountain is capped, the clouds will not thicken; Or the "mountain with a hat" where clouds rise after rain is not a sign of rain. Therefore, there is a saying that "there is a rainy mountain wearing a hat, and the hat is lifted quickly."

The clouds around the waist are generally local clouds produced by nighttime cooling. The clouds are not thick, and when the sun rises, the clouds will disperse, and it will be sunny in the future.

"it will be cloudy if it is sunny for a long time, and it will be sunny if it is rainy for a long time": it will be foggy if it is sunny for a long time, indicating that the weather will turn rainy or rainy in the future; The fog after a heavy rain indicates that it will be sunny or sunny in the future. There are many proverbs: Don't go out at sunrise, but go to Wan Li Road at sunset.

Scientific truth:

In the morning or evening, the sun shines obliquely, and the distance through the air layer is relatively long, and the scattering is greatly weakened. In the solar light wave, purple is weakened the most, followed by indigo and blue, and red or orange light is weakened the least. These weakened colored sunlight shines on the sky and clouds, forming bright and dazzling rosy clouds.

In the morning of spring and summer, the low-altitude air is stable and there is little dust. If there is a bright morning glow, it means that there are many water drops and clouds in the eastern low altitude, and the bad weather will gradually approach. This is the reason why the morning glow never dies; At night, due to the sunshine heating in one day, the temperature is high, and there is generally not much water vapor in the low-altitude atmosphere, but due to the weakening of convection, dust may be concentrated in the lower level in large quantities. If there is a bright sunset glow, it is mainly caused by the scattering of sun light by dry particles such as dust, indicating that the weather in the west is relatively dry. According to the law of airflow moving from west to east, the local weather will not get worse in the future, so there is a saying that "the sunset clouds travel along Wan Li Road". Of course, this is just a general rule. You really need to grasp the appearance of God and take the lead in traveling.

"Clouds are hanging in the sky, and rain is dripping on the ground": Hook clouds are called hook cirrus clouds in meteorology, which generally appear in front of warm fronts and low pressure, indicating that front or low pressure is coming, which is a harbinger of rain. But after rain or winter, there will be sunny days or frost one after another; Hook clouds dissipate, sunny days are drier ","winter hook clouds, sun dust "proverb.

"The clouds go east and the wind blows; Clouds go west and wear hemp fiber ":The clouds here refer to the low clouds in the low-pressure area. The low pressure is from west to east (in fact, it often moves from southwest to northeast). The cloud goes west, indicating that this place is in front of the low pressure, because it will rain locally; The cloud is moving eastward, indicating that the low pressure has moved past the local area, and the local area is behind the low pressure. The weather is going to clear up, and a strong wind often blows before it clears up.

"Dark clouds cover the morning, and the wind will come even if it doesn't rain": It means that there are dark clouds covering the sun in the southeast in the morning, which indicates rain. Because the warm and humid southeast wind blows in the morning, the temperature is higher than the local air, which causes the upper part to be cold and the lower part to be hot, and the water vapor easily rises into clouds. In addition, during the day, the ground is heated, and the air convection rises, which further promotes the clouds to rise. When it meets cold water vapor, it becomes water droplets, which may make it windless and rainy.

Wearing a hat on the mountain means that the air pressure is low, and most of the water vapor in the air forms clouds at the top of the mountain. As for whether it will rain, it generally depends. If the clouds gradually decrease and thicken, there is a great possibility of rain. On the contrary, if the clouds gradually rise and thin, the possibility of rain is small.

There are clouds hanging in the sky and rain dripping on the ground. -There are white clouds hanging in the sky with one end hooked, which are usually generated in front of the front, so it indicates that the front is coming and there may be rain in the future. The front is the interface of cold and warm air in meteorology, and there are often weather phenomena such as precipitation and strong wind.

2. Fish scale day, even if it doesn't rain, the wind will jump-fish scale day means that the clouds in the sky are arranged in the sky like fish scales, not as big as fish and carp, but smaller. Meteorologically, this kind of cloud is called cumulus, which mostly appears at the front of low pressure. Generally, it means that there will be a low pressure moving northward in the next 24 hours, the sky will be unstable and the weather will improve.

Dark clouds rise at sunset, and the sound of rain rings at midnight-at sunset, dark clouds meet drivers. This dark cloud is actually a kind of low black cloud, which shows that the rain in the west, southwest and southeast moves quickly, the dark cloud develops upwards and the humid air comes up from the south. In the future, the low pressure will move to this station, and it will rain.

There are three fogs, and the light rain can't stop-there are fogs for several days in a row, indicating that the local area is in the confrontation zone of cold and warm air. Warm air is full of water vapor, and cold air leads to cooling, which is an excellent condition for fog. The confrontation between cold and warm air often brings rainy weather.

5, the sunrise is a little red, no rain is the wind-the sunrise is red, indicating that there is a lot of water vapor in the air (sunlight scatters when it passes through water vapor, only red light can reach our eyes). Such rich water vapor is usually caused by rainy weather, so it is a sign that wind and rain are coming.

6. Look at the southeast early and the northwest late-the air in the atmosphere also moves from west to east with the earth. Looking at the northwest at night, if there are dark clouds rolling in the northwest sky, it means that precipitation will move into the local area in the future and the weather will get worse. If the weather in the northwest is fine, the weather will improve in the future. Get up in the morning to see the southeast. If the weather in the east is sunny, it means that the bad weather will pass and the weather will get better in the future. If the weather in the east is bad, it is likely to get worse as the weather in the south develops northward.

7. There is a rainy mountain wearing a hat, and there is no rain cloud around its waist-the cloud covers the top of the mountain and is called "the mountain with a hat". Clouds block the mountainside and you can see the top of the mountain, which is called "clouds in the middle".

When rainy weather comes, the clouds are very low and the bottom of the clouds covers the top of the mountain. The thicker the clouds are, the lower the clouds are, indicating that the more water vapor in the air, the easier it is to form rainy days. However, if the mountain is capped, the clouds will not thicken; Or the "mountain with a hat" where clouds rise after rain is not a sign of rain. Therefore, there is a saying that "there is a rainy mountain wearing a hat, and the hat is lifted quickly."

The clouds around the waist are generally local clouds produced by nighttime cooling. The clouds are not thick, and when the sun rises, the clouds will disperse, and it will be sunny in the future.

8. Aconitum wind and white head rain-"Aconitum" and "white head" refer to the cloud top color of two clouds. Aconitum is a kind of cumulonimbus, and Whitehead is a kind of cumulonimbus. These two kinds of clouds often appear in summer. "Aconitum" cloud, with flat bottom and convex top, is mainly composed of water droplets. Water droplets in the cloud absorb and scatter some sunlight, making the bottom and top of the cloud look dark. The top of the "Whitehead" cloud rises. Due to the strong air convection, the vertical development is rapid, the clouds are getting higher and higher, and the cloud top diffusion is very vigorous. It soon occupied most of the sky. The cloud top is a structure of ice crystals, so it is white.

Compared with these two kinds of clouds, the "Aconitum" cloud is not as prosperous as the "Whitehead" cloud, so there is generally little or no rain, and only a gust of wind blows, so it is called "Aconitum Wind". But if the "Aconitum" cloud develops vigorously and gradually becomes a "bald" cloud, it will cause a strong thunderstorm, so it is called "bald rain".

9. It rains in the morning and sunny at night-the rainbow appears in the opposite direction of the sun. In the morning, the sun is in the east and the rainbow is in the west. In the afternoon, the sun is in the west and the rainbow is in the east. Because the weather system moves regularly, it moves from east to west and a rainbow appears in the west. It shows that the thunderstorm area in the west will move, there will be rain in the local area, and there will be rainbows in the east, which means that the rain area will move eastward and will not affect the local area. So it is also called "East Rainbow Sun, West Rainbow Rain".
